Easy to say the least.
"You should try changing the spark plugs in a e60m5 , or a 645i its great crack .
But not nearly as much fun as replacing the starter in the e60 m5 .
For those that dont know its a v10, now where do you think they might hide the starter , yes you guessed it , under the plenum !
So you remove the plenum , with 10 hidden jubilee clips holding it to the throttle bodys , and the air boxs ,, and the numerous other little hoses attached to the plenum with "quick connectors " sure they are quick connections when you can actually get to them , any way plenum off and you are greeted with a large plastic box that contains the wiring harness and runs the full lenght of the valley so you cant get near the starter , so just move the wiring harness right , WRONG there is no slack on ANY connections , so you have to unplug all the vanos , knock sensors throttle actuators ect ect
then you can take out the starter right !WRONG !!
You have to remove the idle control valve ,so now you can remove the starter , well you could if you could get to the bolts ,
so up in the air with the car and remove the exhaust system from the manifolds back , remove all the under tray ( with the eight million bolts and clips ) remove the prop shaft remove the gearbox mount and let the engine and box angle down , then get you ten foot extension bar to reach the two main bolts holding the starter and remove them , then drop the car back down and remove the little allen kew bolt thats hidden from view .
Now you can remove the pittful excuse for a starter , I swear its like something you would see on a little jap yoke ."
